Curtain

ABSTRACT

A curtain includes a fixing rod and a curtain body. The fixing rod is secured at an upper side of a window frame, consisting of a winding shaft in its interior and an endless bead string wound movably on one end of the winding shaft. The curtain body is made of a plurality of flexible strings intertwined with one another to form innumerable string circles and pores of various sizes between the string circles. Then the upper end of the curtain body is fixed on the winding shaft so that the curtain body may be pulled up and down by rotation of the winding shaft by pulling the bead string. The pores functions to let the curtain body have proper airiness and light passing through.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a curtain, particularly to one having innumerable pores to produce airy and light-passing effect in addition to a sound insulating function.

2. Description of the Prior Art

There are quite many styles of curtains widely used, such as a winding one, a pulling one, a Venetian, almost made of cloth to provide with blocking function for sunlight to prevent furniture from gradually deforming or disfiguring caused by direct shining of sunlight, and keeping the room temperature from getting higher at the same time, so persons in a room may feel comfortable.

However, conventional curtains generally have the following disadvantages.

1. A curtain body has tiny pores to cause deficient airiness so ventilation is very bad, specially, if its weaving density is high, the curtain is much worse in ventilation.

2. A curtain body has tiny pores capable to block light from shining in, so if light is much needed, the curtain cannot be used, and if the curtain is half opened to let light or air coming in, privacy is not so good.

3. Conventional curtain material has worse function in sound absorbing.

4. Conventional curtain bodies are generally made of material of small specific gravity, subject to wind blowing and resulting in the curtain body being easily broken or things in a room apt to be blown down by a wind to break.

SUMMARY OF THE INVENTION

This invention has been devised to offer a curtain having a fixing rod and a curtain body. The fixing rod is located at an upper side of a window frame, and the curtain body is made of a large number of flexible threads intertwined with innumerable irregular solid thread circles and pores formed. The upper end of the curtain body is connected on a winding shaft of the fixing rod.

The curtain according to the present invention has proper airiness and light passing caused by the innumerable pores and fine sound insulating function as well. In addition, the curtain body can be wound down naturally and flatly, applicable widely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A preferred embodiment of a curtain in the present invention, as shown in FIGS. 1 and 2, includes a fixing rod 11 and a curtain body 12 combined together.

The fixing rod 11 is secured at an upper side of a window frame (not shown), consisting of a winding shaft 111 and an endless bead string 112 wounded around one end of the winding shaft 111 so as to wind the winding shaft 111 and consequently the curtain body moving up and down.

The curtain body 12 is made of many flexible threads 121 intertwined to form innumerable irregular solid thread circles 122 and innumerable pores 123 of diverse sizes formed between the circles 122. Then one surface of the curtain body 12 is pressed with heat to become a flat surface 124 so as to decrease properly the number of the pores 123 so light passing through the pores 123 may be lessened. Moreover, the other surface of the curtain body 12 is kept as ever, still having a large area for sunlight to pass through with the pores 123 all intact. At the same time, the curtain body 12 has a comparatively large specific gravity, enable the curtain body 12 to move down naturally and smoothly, and not apt to be blown by a wind to swing wildly.

Next, the curtain 10 in the invention can be operated in almost the same way as the conventional one, by pulling the bead string 112 to rotate the winding shaft 111 to wind up the curtain body 12 up or move down.

In addition, FIG. 3 shows a curtain body 12 of a second embodiment of a curtain in the invention, having two surfaces of the curtain body 12 pressed with heat to become two flat surfaces 124 so that the pores 123 in the two surfaces 124 are decreased to the minimum as possible to restrict sunlight to pass through at the so the curtain body 12 may have comparatively good effect for blocking light, preferably applicable to buildings receiving strong sunlight.

Next, FIG. 4 shows a third embodiment of a curtain body 12, which a net 125 is additionally provided on one surface for strengthening connection of each thread circles 122, and then the curtain body 12 may have more strength to resist pulling, and subsequently avoiding breakage from pulling.

Finally, FIG. 5 shows a fifth embodiment of a curtain 20 in the present invention, which is a Venetian style, including a fixing rod 21, and a curtain body 22.

The fixing rod 21 consists of a winding shaft 211 and an endless bead string 212 wound around one end of the winding shaft 211. The Venetian curtain 22 has its lower end connected with a lower horizontal rod 221, and a plurality of folding horizontal rods 222 spaced apart equidistantly between the upper end and the lower end of the Venetian curtain 22. Each folding rod 222 is provided with two string ears 223 for two strings 224 respectively to pass through, with the upper end of each string 224 fixed on the winding shaft 211 and with the lower end thereof fixed on the lower rod 221. Then when a user pulls the bead string 212 up or down, the winding shaft 211 is rotated to wind up the two strings 224 at the same time, with the lower rod 221 being pulled up or down to push up or pull down the folding rods 222 in order.

Further, it is also necessary to know that the curtain body 12 (22) of the curtain 10 (20) can in advance be made by cutting into a plurality of lengthwise elongate strips (not shown), and then fixed on the fixing rod 11 (21), which is then secured at an upper side of a window frame to become a complete curtain provided with functions of blocking insects from entering and lessening sunlight shining in.

The invention has the following advantages, as can be understood from the aforesaid description.

1. The curtain body 12 (22) can be made to having proper airiness and light-passing by designing the necessary sizes of the pores 123 so that the curtain body may have good ventilation in case of completely shuttering a window, still possible to let light passing through without the drawbacks of the conventional curtains that should be properly shut or opened to let more light enter, causing bad privacy.

2. The curtain body 12 (22) has a comparatively better function of sound absorption and insulation for keeping a room quiet.

3. The curtain body 12 (22) is comparatively heavy so that it can naturally move down to form a flat condition, not apt to be blown to move wildly by a wind without breakage and thus prolonging its using life.
